MACHINE FOR TREATING STRIPS OF HORN OR OTHER MATERIAL.

SPECIFICATION forming part of Letters Paten NO- 771,082, dated September27, 1904.

Application filed October 28, 1903. Serial No. 178,864. (No model.)

To U whom it may concern.-

Be it known that I, J AMES F. MARTIN, a citi- Zen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Machines for TreatingStrips of Horn or other Material, of which the following is aspecification.

My invention consists of an improvement in a machine for treating hornand similar substances wherein I provide two surfaces movably connectedwith means for heating the same and between which the horn or othersubstance to be treated is inserted.

It further consists of novel details of construction, all as will behereinafter set forth.

Figure 1 represents a top plan view of the machine embodying myinvention. Fig. 2 represents a partial side elevation and partialsectional view of the machine. Fig. 3 represents a sectional view online :0 m, Fig. 1.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates an apparatus for treating hornor other material consisting of the body portion or frame B, forming achamber C, the upper portion of which is closed by the plate D, whichserves as a table or support for the movable blocks E, which are adaptedto normally rest adja cent said plate.

F designates a gas-pipe which passes beneath the plate D and isconnected with a suitable source of gas-supply, being provided with asuitable Bunsen burner G to properly control the flame to be directedagainst the plate D.

H designates standards connected with or forming part of the bodyportion B, in which standards is journaled the pin or other suitablefastening device J, said pin passing between lugs K, projecting from theblocks E, whereby it will be seen that the blocks can be tilted slightlyin either direction and are freely connected with the body portion ofthe apparatus, but cannot be displaced therefrom'until the pin J isremoved from between the lugs, when any one of the blocks can be quicklyand easily removed and a new one placed in position, if desired. In thepresent instance I have shown the lower portion of the blocks providedwith shoulders L, which are adapted to rest upon the lugs or tracks M,projecting from the upper portion of the plate D, it being seen that inthis manner the blocks cannot be moved longitudinally or transversely onthe machine, while at the same time they can absorb heat from the plateDthrough the medium of the lugs M.

The operation is as follows: I have found in the treatment of horn thatit is necessary to apply a certain amount of heat in order that the horncan be handled, and it is usually necessary that both sides thereof beheated to the same degree. I have found also that it is of advantage toplace the horn to be treated between two surfaces which are ofsubstantially the same degree of heat. By lighting the pipe F the flametherefrom heats the plate D, which in turn heats the plates or blocks E,and by inserting a piece of horn, as shown at Nin Fig. 3, between anyone of the blocks E and the plate D the same will be heatedsubstantially the same degree on both sides.

I have shown the front lower edge of the block as inclined or curved, asat P, in order to permit the easy insertion of the horn; but it will beevident that there may be various changes made in construction as hereinshown and described which will come within the scope of my invention,and I do not, therefore, desire to be limited in every instance to theexact form as I have shown. It is to be noted that the blocks E are allmounted loosely to assume their lowermost position by gravity, and thenecessity of screw-rods and the like is dispensed with, the blocks beingraised by the insertion of the strip of horn under the same, as seen inFig. 3.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an apparatus for treating horn or similar material, a plate, meansfor heating the same and a gravitating block suitably supported adjacentsaid plate for free vertical movement and adapted to receive its heattherefrom.

2. In an apparatus for treating horn or similar material, a plate, meansfor heating the same, a gravitating block, and means for supporting thesameadjacent said plate for free vertical movement whereby the articleto be treated can be inserted therebetween.

3. In a device of the kind specified, a plate, means for heating thesame, a gravitating block adapted to be supported by said plate for freevertical movement and means for holding said block in position andpreventing movement thereof.

4. In adeviee of the kind specified, a plate, means for heating thesame, a gravitating block loosely mounted on said plate for freevertical movement and means embracing said block for conveying heatthereto.

5. In a device of the kind specified, a plate, means for heating thesame, a gravitating block adapted to be supported on said plate for freevertical movement, lugs on said block and a pin suitably supported andadapted to be situated loosely between said lugs for holding said blockin position.

6. In an apparatus for treating horn orsimilar material, a plate, meansfor heating said plate and a gra\ *itating block suitably supportedadjacent said plate for free vertical movement and adapted to be heatedby substantial contact therewith.

7. In an apparatus for treating horn or similar material, a plate, meansfor heating said plate, a gravitating block mounted on said plate forfree vertical movement so that an article to be treated may be placedtherebetween and means for imparting heat from said plate to said blockwhen said article is so placed.
